200530675 九、發明說明： 【發明所屬之技術領域】 本發明係關於-種顯示面板及顯示裝置，其係如同(三 次元立體）顯示能夠針對多數視點進行不同的圖像顯示。 【先前技術】 由於人類的雙目艮彼此具有空間上的距離而位在頭部，因 此在通常的視野中，乃憑藉2個不同視點所見而感知物像， 人類的大腦便藉由該等2個物像之視差而辨識立體感。於是 有人利用此原理開發出-種液晶顯示裝置，其係使觀察者 視認從左右眼互異的視點所見之物像而賦予視差，藉此進 行3D(三次元立體）顯示。 於進行3D顯示之液晶顯示裝置中，為針對觀察者之左右 眼供應視點不同之圖像，其方法例如是以顏色、偏光狀態 或顯示時刻將顯示畫面上左眼用之圖像及右眼用之圖像進 行編碼，藉由觀察者配戴之眼鏡狀濾光系統將該兩者分 離’而單獨供應對應各眼之圖像。 此外亦有如圖8(a)所示之液晶顯示裝置，其係將成條狀形 成光線透過區域及遮斷區域之視差屏障1〇2組合於液晶顯 示破置之顯示面板1 〇 1上，則在觀察者側即使不使用濾光系 統等視覺輔助器具，亦可辨識3D圖像（自動立體顯示）。亦 (7藉由視差屏障1 02針對顯示面板1 〇 1上產生之右眼用圖 像及左眼用圖像賦予特定之視角，只要從空間上之特定觀 察區域觀看，僅會視認出各自對應左右眼之圖像，而使觀 察者辨識出3D圖像（參照圖8(b))。 97367.doc 200530675 此外，使用與上述3D顯示相同之技術，亦可製作出如下 之顯示裝置：從左右互異之方向觀看同一顯示畫面之情形 時’針對來自不同方向的視認而顯現不同之影像。亦即， 如同使用視差屏障而以3D顯示分離圖像之情形，無需區分 右眼用圖像及左眼用圖像，只要顯示各自相異之圖像，即 可將不同之影像供應給從左右不同的方向觀看同一顯示書 面之多位觀察者。 八口+公開公報之曰本專利特開平8-1 10495號公報（公 開曰1996年4月30曰）中，揭載使用液晶面板及視差屏障之 3D顯示裝置之串擾問題。換言之，於上述公報中揭載出在 3D顯示裳置中’存在有無法以單眼觀測右眼用圖像及左眼 用圖像兩者之立體視覺區域，此種右眼用圖像與左眼用圖 像之重疊即稱作串擾。 回 惟於日本專㈣開件謂95號公報中，扣顯示裝置之 串擾係藉由視差屏障之開口部之開口率而決定，直中 於該公報所揭載之最佳觀察位置不會發生串擾。 :外，於上述之3D顯示裝置及對多位觀察者供 像之顯示裝晉中所您田 — ^ 同n 之顯不用液晶面板之構造基本上相 為用液晶面板中之各像素圖案例如是由τ 透明像素電極而構成。此外，各 線與多條源極線相互交叉之位置/圖案係設於多條開極 離。 τ朕（禾圖不）予以絕緣分 通4由於像素電極與對 此外，於該種液晶顯示面板中 97367.doc 200530675 向電極（未圖示）之間的液晶電容不足，故與閘極線並聯設置 輔助電容線，並將TFT元件之㈣電極延伸至辅助電容線而 藉此形成重疊部，而將形成於其間之絕緣膜作為介電體而 形成輔助電谷（電何保持用電容器）。 然而本申請案發明者發現，在3〇顯示裝置中使用上述先 前之液晶顯示面板之情形中，即使在日本專利特開平 8] 10495號公報中推定不會發生串擾之最佳觀察位置，仍 會發生串擾而導致顯示性能低落。 亦即，在上述液晶顯示面板之各像素圖案中，作為光線 透過區域之開口部在TFT元件或輔助電容之配置因素下不 會形成矩形，基於TFT元件或輔助電容之配置位置及其形狀 等主要原因，於局部會出現具有狹縫之開口部之情形。 此外，當光線通過隔著規則間隔之細小開口部時，由於 其行進方向具有彎曲性質（即繞射5見象），故於像素圖案中具 有該種狹縫開口部之情況下，通過該該開口部之光線會產 生繞射現象。 因此，如圖9所示’例如在組合視差屏障與顯示用液晶面 板而成之3D顯示裝置中，當利用通過上述視差屏障而賦予 特定視角之光線通過顯示用液晶面板中之狹縫開口部時引 起繞射現象之情況下，「左眼用光線」與「右眼用光線」 無法完全分離而發生光學性串擾，結果便產生犯顯示性能 低落之問題。 具體言之，除了通過視差屏障而被賦予特定視角之光線 (圖9中以虛線箭頭表示）以外，若於通過狹縫開口部時產生 97367.doc 200530675 繞射光（圖9中以實線箭頭表示）， ’…"亥、、堯射光會產生對觀察 用=眼供應左眼關像、或者對觀察者的左眼供應右眼 =:作用(本說明書中將此種光學作用稱作串擾)。在此 -用下’於3D顯不時會觀測到奇異的圖像。又，在 ^位觀察者供應不同圖像顯示時亦會產生相同的問題， ^看到其中一者顯示圖像與另-者顯示圖像重疊之圖像。 :’由上述繞射現象所造成之串擾並非視差屏障方式 :特有之問題’在透鏡陣列方式、眼鏡方式等方式中亦會 生’此外不僅是將顯示圖像同時分離成多個視點之方 式，在將顯示圖像分時分離成多 【發明内容】 们視點之方式中亦會產生。 f發明係為解決上述問題點而提出，其目的在於提供一 種此抑制因繞射現象而生之串 欠改善3D顯示或對多位觀 察者供應不同影像之顯示性能之顯示面板及顯示裝置。 為達成上述目的，本發明 板具有對應輸入之圖 士 生顯示圖像之顯示圖像產生手段、及同時或分 ㈣㈣示圖像分離成多個視點之顯示圖像分離手段，其 特被在於上述顯示圖像產生手段係主動矩陣型顯示面板， 矩陣型顯示面板之各像素圖案中之開口部之寬度係 吕又疋為： =象素之開口部之最小寬度）/(像素之開口部 度）S 0.037 ;或者 像素之開口部之最小寬度)/(像素之開口部之最 大寬度）<1。 取 97367.doc 200530675 根據上述構造，冑由將各像素圖案之圖案中之開口部寬 度設定在上述之範圍内，即可使用上述顯示面板將同時或 分時將顯示圖像分割成多個視點進行顯示時因繞射現象產 生之串擾值控制在5.6以下’而能夠降低對視認性的不良影 響。 此外，為達成上述目的’本發明之其他顯示面板具有對 應輸入之圖像資料而產生顯示圖像之顯示圖像產生手段、 及同時或分時將該顯示圖像分離成多個視點之顯示圖像分 離手段，其特徵在於上述顯示圖像產生手段係主動矩陣型 顯示面板，該主動矩陣型顯示面板之各像素圖案中之開口 部之寬度係設定在非以下之範圍： 2 μιη<(像素之開口部之最小寬度）<7 μιη。 根據上述構造，藉由將各像素圖案之圖案中之開口部寬 度設定在上述之範圍内，即可使用上述顯示面板將同時或 分時將顯示圖像分割成多個視點進行顯示時因繞射現象產 生之串擾值控制在5.6以下，而能夠降低對視認性的不良影 響。 〜 此外，為達成上述目的，本發明之其他顯示面板具有對 應輸入之圖像資料而產生顯示圖像之顯示圖像產生手段、 及同時或分時將該顯示圖像分離成多個視點之顯示圖像分 離手段，其特徵在於上述顯示圖像產生手段係主動矩陣型 顯示面板，並以遮光膜將該主動矩陣型顯示面板之各像素 圖案中之狹縫開口部予以遮光。 根據上述構造，若於上述像素圖案中具有開口部，因而 97367.doc -10- 200530675 會因繞射現象產生_擾而對視認性帶來不良影響之情彤 時，以遮光膜覆蓋該開口部，藉此遮斷造成串擾之要因= 繞射光，即可防止因繞射現象而產生串擾。 本發明的其他進一步之目的、特徵及優點，應可透過以 下敘述而獲得充分理解。此外，本發明之效益可從以下參 照附件圖式之說明中得知。 【實施方式】 針對本發明之一實施形態，根據圖式說明如下。 首先參照圖2，說明本實施形態之2〇/3]〇切換式液晶顯示 面板之概略構造。又，本實施形態係舉例表示將本發明之 液晶顯示面板應用於2D/3D切換式液晶顯示面板之情形者。 上述2D/3D切換式液晶顯示面板如圖2所示，其係貼合顯 示用液晶面板（顯示圖像產生手段）1〇、圖案化相位差板（視 差屏障手段）20、及切換式液晶面板3〇而構成。此外，針對 本實施形態之2D/3D切換式液晶顯示面板，提供安裝有驅動 電路及背光（光源）等之2D/3D切換式液晶顯示裝置。 顯不用液晶面板1〇係設置作為TFT液晶顯示面板，其疊 層有第1偏光板11、對向基板12、液晶層13、主動矩陣型基 板 14 及第 2偏光板 15，介以 Fpc(Fiexible printed circuits， 幸人|±印刷電路板）等之配線5丨對主動矩陣型基板14輸入對 應於所要顯示的圖像之圖像資料。此外，於第2偏光板15 之表面被覆有丙烯酸系樹脂膜16作為有機膜。 圖案化相位差板20係作為視差屏障之一部分發揮功能 者，如圖3(a)所示，其係於透明基板21上形成配向膜22，並 97367.doc 200530675 進步於其上疊層液晶層23而構成。此外，於上述圖案化 差板20之有效顯示區域中，如圖3(b)所示，由偏光狀態 互…之第1區域2〇A(圖中以斜線部表示）與第2區域2〇B(圖 t以網點部纟示）交互形成長條&。再者，於圖案化相位差 板中σ又有以與第1區域20A相同工序而形成之對準記號 20C。 切換式液晶面板30疊層有驅動側基板3丨、液晶層32、對 向基板33、及第3偏光板34，於驅動側基板31上連接用以於 液阳層32導路時施加驅動電壓之配線52。 切換式液晶面板30係配置作為切換手段，其係對應液晶 層32之通路/斷路，將透過該切換式液晶面板3〇之光線切換 為偏光狀恶。亦即，切換式液晶面板3〇係在2〇顯示時及3D 員示時對透過该切換式液晶面板3 〇之光線進行不同的光 予凋夂作用。又，切換式液晶面板3 〇無需進行如顯示用液 晶面板ίο之矩陣型驅動，因此驅動側基板31及對向基板w 中所含之驅動電極只要於該切換式液晶面板3〇之有效顯示 區域全面形成即可。 其次’針對上述構造之2D/3D切換式液晶顯示面板之顯示 動作進行說明。 首先，於圖2所示之2D/3D切換式液晶顯示面板中，以圖4 例不各構成構件之光學軸之方向。又，於圖4中表示之光學 軸，在液晶面板及相位差板上係配向膜之遲相軸方向（即相 對於配向膜之摩擦配向方向），在偏光板上則為透過軸之方 向0 97367.doc -12- 200530675 在圖4之構造中，來自光源之入射光起初會由切換式液晶 面板30之第3偏光板34使其偏光。此外，切換式液晶面板3〇 在3D顯示時於斷路狀態下作為1/2波長板發揮作用。 - 此外，通過交換式液晶面板3〇之光線會接著入射到圖案 化相位差板20。圖案化相位差板2〇之第i區域2〇A及第2區域 — 2 0B由於其摩擦配向方向、即遲相軸之方向不同，故通過第 1區域20A之光線與通過第2區域2〇B之光線兩者之偏光狀 態不同。在圖4之例中，通過第！區域2〇A之光線與通過第2 ^ 區域20B之光線·之偏光軸相差9〇。。此外，圖案化相位差板 20係根據液晶層23之複折射率異方性及膜厚而設定作為 1/2波長板發揮作用。 通過圖案化相位差板20之光線係入射至顯示用液晶面板 1 0之第2偏光板1 5。於3D顯示時，通過圖案化相位差板2〇 之第1區域20A之光線之偏光軸與第2偏光板丨5之透過軸平 行，通過第1區域20A之光線會透過偏光板15。另一方面， 通過第2區域20B之光線之偏光軸與第2偏光板丨5之透過軸 _ 成90角，通過第2區域20B之光線不會透過偏光板15。 亦即，在圖4之構造中，藉由圖案化相位差板20與第2偏 光板15之關聯性光學作用而達到視差屏障功能，使圖案化 相位差板20之第i區域20A成為透過區域、第2區域2〇b成為 遮斷區域。 · 通過第2偏光板15之光線會在顯示用液晶面板1〇之液晶 · 層13中進行黑色顯示之像素與進行白色顯示之像素受到不 同之光學調變，而僅有藉由進行白色顯示之像素予以光學 97367.doc -13· 200530675 凋邊之光線會透過第1偏光板1 i，藉此進行圖像顯示。 此日守通過上述視差屏障而被賦予特定視角之光線於顯 不用液晶面板10中會通過各自對應於右眼用圖像及左眼用 圖像之像素，藉此使右眼用圖像與左眼用圖像分離為不同 之視角而進行3D顯示。 此外，於進行2D顯示之情形時，切換式液晶面板3〇轉為 通路，不對通過該切換式液晶面板3 〇之光線施行光學調 變。通過切換式液晶面板30之光線則藉由接著通過圖案化 相位差板20分成通過第1區域2〇a之光線與通過第2區域 20B之光線，而被賦予不同之偏光狀態。 然而，2D顯示之情形不同於3D顯示之情形，其不具有切 換式液晶面板30之光學調變作用，因此通過圖案化相位差 板20之光線之偏光軸會產生相對於第2偏光板丨5之透過軸 之左右對稱之角度偏差。因此，通過圖案化相位差板2〇之 第1區域20A之光線與通過第2區域2〇B之光線會以相同之 透過率透過第2偏光板15，圖案化相位差板2〇與第2偏光板 15之間不會產生關聯性光學作用而達成視差屏障功能（未 被賦予特定之視角），故為2D顯示。 又’於上述說明中’乃例示將本發明應用於2D/3D切換式 液晶顯示面板之情形。不過，由於本發明之目的在於防止 3D顯示裝置或者對多位觀察者供應不同影像之顯示裝置之 顯示用液晶面板中因繞射現象而產生串擾，基於此目的， 本鲞明亦可適用於不含切換式液晶面板3 〇之構造（3D顯示 專用之構造）之3D型液晶顯示面板及3D型液晶顯示裝置，或 97367.doc -14- 200530675 者亦了適用於對多位觀察者供應不 一 淼田斟夕々τ ^k 门〜像之顯示裝置（可 採用對夕位硯察者供應不同影像 .^ ”、、貝不與一般顯示之切換 式構，亦可採用對多位觀察者供 > ^、 、應不同影像之顯示專用 之構造）。 此外，將本發明應用於不含切 祐一^ ，夜晶面板之3D型液晶 卜員不面板、或應用於對多位顴家 署…^ 卞夕位觀察者供應不同影像之顯示裝 置之情形時，可設置1/2波長板來 ^ ^ α A t %代切換式液晶面板，使 其遲相軸對準切換式液晶面板 双羊搽配向方向即可。又， 圖2中之第3偏光板34則直接設 ,/0 ,, H ^ % n切換式液晶面板之 1/2波長板之光源側（於圖案化 是扳20中，與顯示用液晶 面板10之貼合面相反側）。 又，本發明不限於上述 要+ ώ 夜日日頌不面板及液晶顯示裝 置，亦適用於不設置切拖式、右曰ζ 1 、弋液日日面板3〇、圖案化相位差板 20而改用遮光性金屬膜或垔辛 飞…、色树月日荨遮光性材料形成視差 二…不面板及顯示裝置，或者以遮光性材料直接於對 ?基板12或‘主動矩陣型基板14上形成長條狀之顯示面板及 =不裝置、。當然，使用該等視差屏障之顯示面板及顯示裝 置’亦可適用於3 D顯示或者真門、隹广 a 一 飞#專門進仃對多位觀察者供應不 同衫像之顯示之顯示面板及顯示裝置。 更且’本發明不限於視差 幵丨早方式，亦可適用於採用透 鏡陣列或眼鏡之方式、乃5 於以刀時且同步之方式將光源 之指向性及顯示影像同時或分 又刀守刀離成多個視點之顯示面 板及顯示裝置。當麸，兮努 _ …、w荨颂不面板及顯示裝置亦可適用 於不分離顯示圖像即可土 口爆PT切換者，且亦可適用於專門顯示分 97367.doc -15· 200530675 離圖像者。 在此，於本發明之液晶顯示裝置中，為防止顯示用液晶 面板中因繞射現象而產生之_擾所需之主要構造在於顯示 用液晶面板。因此，以下將詳細說明本實施形態之顯示用 液晶面板之構造。 本實施形態之顯示裝置中使用之顯示用液晶面板1〇中之 主動矩陣型基板14，其中之顯示用液晶面板之各像素圖案 如圖1所示，包含TFT元件83及透明像素電極86而構成。此 外，各像素圖案係設於多條閘極線80與多條源極線81相互 父叉之位置而形成矩陣狀。閘極線⑽與源極線8 1係藉由設 於该兩者間之層間絕緣膜（未圖示）予以絕緣分離。 此外，於上述液晶顯示面板中，通常由於像素電極86與 對向電極（未圖示）之間的液晶電容不足，故與閘極線81並聯 設置輔助電容線82，並將TFT元件83之汲極電極83c延伸至 輔助電容線而藉此形成重疊部，而將形成於其間之絕緣膜 作為介電體两形成輔助電容84(電荷保持用電容器）。 上述TFT元件83之汲極電極83c藉由於輔助電容84之一部 分之層間絕緣膜上開孔而連接於像素電極86 ;閘極電極“a 連接於供給掃描信號而使TFT元件83通路/斷路之閘極線 8〇’·源極電極83b介以TF 丁元件83而連接於對像素電極輸入 影像信號之源極線8 1。 輔助電容線82係將設在與源極線8 1之交又部之絕緣膜作 為介電體而產生負載電容。為減低該負載電容引起之掃描 信號及影像信號之信號延遲，使源極線81上之輔助電容線 97367.doc -16- 200530675 82之線寬細小化，以期縮小交又部面積而減低負載電容。 此外為確保輔助電容量，使輔助電容84本身儘可能靠近其 兩端之源極線81，藉此擴展寬度而增大面積。換言之，上 述輔助電容線82在與源極線81交叉之處形成較細線寬，於 像素圖案内則形成較粗線寬。 將上述辅助電容84形成上述之形狀，亦即使源極線81上 之輔助電容線82細化而縮小交又部面積，並使辅助電細 靠近兩端之源極線81而擴展寬度，藉此形狀而於cs(輔助電 容）-源極線之間.產生如開σ部88之狹縫開口部。 在圖1所不構造之液晶顯示面板中，於Cs_源極線間形成 之狹縫開口部88中，最大人人士 取大的難碭在於會產生造成上述串擾 的主要原因之繞射現象。 本貫施形態之液晶顯示面板大致提出兩種方法來減輕上 述繞射現象以抑制串擾。 抑制串擾之第1方法是’求出通過狹縫開口部之光線中發 生繞射之條件，*於像素W案之設計階段中設法避免產I 該種狹縫開°部。首先針對此第！方法說明如下。 在此將像素圖案中之狹縫開口部與串擾之關係透過模擬 研究而得之結果揭示如下。首先參照圖5，說明本模擬中使 用之像素圖案。 。η木焚μιη、寬6〇 μηι(為方 說明起見，以長尺寸、宫ρ 4_ 、 寸進行標示），源極線及閘極、《 之各線見尺寸為3 。因此 口此，各像素圖案中由源極線及丨 極線包圍之開口區域之户 匕埝之鉍向取大尺寸為60-3χ2 = 54[μΐΏ]。 97367.doc 200530675 :構=像素圖案中，於上述開口區域内形成輔助 私'構成《助電容之輔助電容線，其線寬在其與源極 狀=又部較細形成。因此，在上述像素圖案中，於ο(輔 助琶朴源極線間產生寬x _之狹縫開口部。在以下之模 擬Γί上述狹縫開口部之寬度又_於〇至27_之範圍内 改受’母次改變，並求出每種情形之串擾值。又，開 口部之寬度X _為〇 _之情形’如圖5(b)所示，是指將輔 助電容線整體形成較粗而未產生狹縫開口部之情形；開口 ^見度Χμ427μηι之情形’如圖5⑷所示，是指將輔助 電谷線整體形成較細而未產生狹縫開口部之情形。 此外，由於上述串擾係於將具有上述像素圖案之顯示用 液晶面板與視差屏障組合而進行3d顯示（或者對多位觀察 者供應不同影像之顯示)之情形時產生，故於以下之模擬 中，將視差屏障之縫隙寬度設為3〇 _、33 _、35 _， 針對此3種情形進行模擬。 一此外，透過模擬而計算出之串擾值係由以下之公式⑴所 疋義之無因次I。X，於該公式⑴中，Dark係於右眼用圖 像及左眼用圖像中之-者進行黑色顯示、另—者進行白色 顯示之情形下表示黑色顯示側之亮度。Β1 —係於右眼用圖 像及左眼用圖像兩者均進行黑色顯示之情形下表示黑色顯 示之亮度。而Bright則是於右眼用圖像及左眼用圖像中—者 進行黑色顯示、另-者進行白色顯示之情形下表示白色顯 示側之亮度。由於發生之串擾越大，在該串擾之影響下則 Dark之亮度越高，使得之值之差距變大故以 97367.doc * 18 -

Description of the invention: [Technical field to which the invention belongs] The present invention relates to a display panel and a display device, which are similar to (three-dimensional stereo) display and can display different images for most viewpoints. [Previous technology] Because human binoculars have spatial distances from each other and are located on the head, in the ordinary field of vision, the object image is perceived by two different viewpoints, and the human brain uses these 2 Distinguish the three-dimensional effect by the parallax of individual objects. Therefore, some people have developed a liquid crystal display device based on this principle, which allows observers to recognize object images seen from mutually different viewpoints of the left and right eyes and give them parallax, thereby performing 3D (three-dimensional stereo) display. In a liquid crystal display device that performs 3D display, for the left and right eyes of an observer, images with different viewpoints are provided. For example, the method is to use the color, polarization state, or display time to display the left-eye image and the right-eye image on the display screen. The images are encoded, and the two are separated by a spectacle-like filter system worn by the observer, and the images corresponding to each eye are separately supplied. In addition, there is also a liquid crystal display device as shown in FIG. 8 (a), which combines a parallax barrier 10 formed in a strip shape to form a light transmission region and an interruption region on a liquid crystal display broken display panel 101. The observer can recognize 3D images (autostereoscopic display) without using visual aids such as a filter system. Also (7) The parallax barrier 102 is used to give a specific perspective to the right-eye image and left-eye image generated on the display panel 10, as long as they are viewed from a specific observation area in space, only their respective correspondences will be recognized. The left and right eye images allow the observer to recognize the 3D image (see Figure 8 (b)). 97367.doc 200530675 In addition, using the same technology as the 3D display described above, the following display devices can also be produced: When viewing the same display screen in different directions, 'different images are displayed for viewing from different directions. That is, as in the case of using a parallax barrier to separate images in 3D, there is no need to distinguish between a right-eye image and a left Ophthalmic images, as long as different images are displayed, different images can be supplied to multiple observers who view the same display from different directions from left to right. No. 10495 (published on April 30, 1996) discloses the problem of crosstalk in a 3D display device using a liquid crystal panel and a parallax barrier. In other words, the 3D display skirt is disclosed in the above publication. There is a stereoscopic area in which both the right-eye image and the left-eye image cannot be observed with one eye. Such an overlap of the right-eye image and the left-eye image is called crosstalk. Back to Japan In the special publication No. 95, the crosstalk of the buckle display device is determined by the opening ratio of the opening of the parallax barrier, and crosstalk will not occur at the optimal observation position disclosed in the bulletin. In the above-mentioned 3D display device and display device for multiple observers, the image of Jinzhong Shoutian — ^ The structure of the LCD panel with n is basically the same as that of each pixel pattern in the LCD panel. For example, it is transparent by τ The pixel electrode is formed. In addition, the positions / patterns where each line and a plurality of source lines cross each other are provided at a plurality of open electrodes. Τ 朕 (Hetu not) is insulated and separated. 4 In this type of liquid crystal display panel, 97367.doc 200530675 the liquid crystal capacitor between the electrodes (not shown) is insufficient, so an auxiliary capacitor line is provided in parallel with the gate line, and the ㈣ electrode of the TFT element is extended to the auxiliary capacitor line, thereby forming Overlap, and The insulating film formed therebetween serves as a dielectric to form an auxiliary valley (capacitor for holding electricity). However, the inventor of the present application has found that in the case where the above-mentioned previous liquid crystal display panel is used in a 30 display device, even in the case of Japanese Patent Laid-Open No. 8] 10495 is estimated to be an optimal observation position where crosstalk does not occur, and crosstalk may still occur, resulting in poor display performance. That is, in each pixel pattern of the above-mentioned liquid crystal display panel, as a light transmission region, The opening does not form a rectangle under the configuration of the TFT element or the auxiliary capacitor, and based on the configuration position and shape of the TFT element or the auxiliary capacitor, an opening with a slit may appear locally. In addition, when light When passing through small openings at regular intervals, the direction of travel is curved (that is, diffraction is visible). Therefore, if there are slit openings of this kind in a pixel pattern, the light passing through the openings Diffraction will occur. Therefore, as shown in FIG. 9, for example, in a 3D display device in which a parallax barrier and a liquid crystal panel for display are combined, when light with a specific viewing angle passed through the parallax barrier is passed through a slit opening in the liquid crystal panel for display In the case of causing the diffraction phenomenon, "the light for the left eye" and the "light for the right eye" cannot be completely separated and optical crosstalk occurs, and as a result, the problem of poor display performance occurs. Specifically, in addition to light that is given a specific angle of view through a parallax barrier (indicated by a dashed arrow in FIG. 9), if it passes through the slit opening, 97376.doc 200530675 is generated (indicated by a solid arrow in FIG. 9) ), '... " Hai, Yao Yao will produce a left eye close-up image for the eye for observation, or a right eye = for the left eye of the observer =: (this optical effect is called crosstalk in this specification) . Here-use 'in the 3D display from time to time, strange images will be observed. In addition, the same problem also occurs when ^ observers supply different image displays, and ^ see an image in which one display image overlaps with the other display image. : 'Crosstalk caused by the above-mentioned diffraction phenomenon is not a parallax barrier method: a unique problem' is also generated in a lens array method, a glasses method, and the like. In addition, it is not only a method of separating a display image into multiple viewpoints at the same time. It is also generated in the method of separating the display image into multiple times according to the present invention. The f invention is proposed to solve the above-mentioned problems, and an object thereof is to provide a display panel and a display device that suppress the string due to the phenomenon of diffraction and improve the display performance of 3D display or supply different images to multiple observers. In order to achieve the above-mentioned object, the board of the present invention has a display image generating means corresponding to the input of the Thompson display image, and a display image separating means for simultaneously or separately separating the display image into a plurality of viewpoints. The display image generating means is an active matrix display panel, and the width of the openings in each pixel pattern of the matrix display panel is Lu Youyi: = minimum width of the pixel openings) / (degree of the openings of the pixels) S 0.037; or the minimum width of the pixel opening) / (the maximum width of the pixel opening) < 1. Take 97367.doc 200530675 According to the above structure, by setting the width of the opening in the pattern of each pixel pattern within the above range, the display panel can be used to divide the display image into multiple viewpoints at the same time or in time. The crosstalk value caused by the diffraction phenomenon is controlled to be 5.6 or less during display, which can reduce the adverse effect on visibility. In addition, in order to achieve the above-mentioned object, the other display panel of the present invention has a display image generating means for generating a display image corresponding to the inputted image data, and a display image for separating the display image into a plurality of viewpoints at the same time or in time. The image separating means is characterized in that the above-mentioned display image generating means is an active matrix type display panel, and the width of the openings in each pixel pattern of the active matrix type display panel is set to a range other than the following: 2 μιη < Minimum width of openings) < 7 μm. According to the above structure, by setting the width of the opening portion in the pattern of each pixel pattern within the above range, the display panel can be used to divide the display image into multiple viewpoints at the same time or in time. The crosstalk value caused by the phenomenon is controlled below 5.6, which can reduce the adverse effect on visibility. ~ In addition, in order to achieve the above-mentioned object, the other display panel of the present invention has a display image generating means for generating a display image corresponding to the inputted image data, and a display that separates the display image into multiple viewpoints at the same time or in time. The image separating means is characterized in that the above-mentioned display image generating means is an active matrix type display panel, and a slit opening portion in each pixel pattern of the active matrix type display panel is shielded by a light shielding film. According to the above structure, if there is an opening in the above pixel pattern, 97367.doc -10- 200530675 may cause disturbance due to the diffraction phenomenon and adversely affect visibility, cover the opening with a light-shielding film. In this way, the cause of crosstalk caused by blocking = diffracted light can prevent crosstalk due to diffraction. Other further objects, features and advantages of the present invention should be fully understood from the following description. In addition, the benefits of the present invention can be learned from the following description with reference to the attached drawings. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings. First, a schematic structure of a 20/3] 0 switching liquid crystal display panel according to this embodiment will be described with reference to FIG. 2. In addition, this embodiment mode shows a case where the liquid crystal display panel of the present invention is applied to a 2D / 3D switching liquid crystal display panel. The 2D / 3D switching liquid crystal display panel is shown in FIG. 2, which is a display liquid crystal panel (display image generating means) 10, a patterned retardation plate (parallax barrier means) 20, and a switching liquid crystal panel. 30 ％。 It is constituted. In addition, the 2D / 3D switching liquid crystal display panel of this embodiment is provided with a 2D / 3D switching liquid crystal display device equipped with a driving circuit, a backlight (light source), and the like. The display liquid crystal panel 10 is provided as a TFT liquid crystal display panel, which is laminated with a first polarizing plate 11, an opposite substrate 12, a liquid crystal layer 13, an active matrix substrate 14 and a second polarizing plate 15, and is interposed by Fpc (Fiexible Printed circuits, Xingren | ± printed circuit board) and other wiring 5 丨 Input active matrix type substrate 14 with image data corresponding to the image to be displayed. The surface of the second polarizing plate 15 is covered with an acrylic resin film 16 as an organic film. The patterned retardation plate 20 functions as a part of a parallax barrier. As shown in FIG. 3 (a), it forms an alignment film 22 on a transparent substrate 21, and 97367.doc 200530675 progresses on the laminated liquid crystal layer. 23 constructs. In addition, in the effective display area of the patterned difference plate 20, as shown in FIG. 3 (b), the first area 20A (indicated by the slanted line in the figure) and the second area 2 are formed by polarized states. B (shown as dots in the figure) interacts to form a strip &. Furthermore, in the patterned retardation plate, σ has an alignment mark 20C formed by the same process as that of the first region 20A. The switching liquid crystal panel 30 is laminated with a driving-side substrate 3 丨, a liquid crystal layer 32, a counter substrate 33, and a third polarizing plate 34. The driving-side substrate 31 is connected to apply a driving voltage when the liquid-yang layer 32 is guided. The wiring 52. The switching liquid crystal panel 30 is configured as a switching means, which corresponds to the path / opening of the liquid crystal layer 32, and switches the light passing through the switching liquid crystal panel 30 to a polarized evil. That is, the switching liquid crystal panel 30 performs different light pre-lighting effects on the light passing through the switching liquid crystal panel 30 during a 20 display and a 3D display. In addition, the switching type liquid crystal panel 3 does not need to perform matrix-type driving such as a display liquid crystal panel ο. Therefore, the driving electrodes included in the driving side substrate 31 and the counter substrate w need only be in the effective display area of the switching type liquid crystal panel 30. Fully formed. Next, the display operation of the 2D / 3D switching liquid crystal display panel with the above structure will be described. First, in the 2D / 3D switching liquid crystal display panel shown in FIG. 2, the direction of the optical axis of each component is exemplified in FIG. 4. In addition, the optical axis shown in FIG. 4 is the late phase axis direction of the alignment film (that is, the frictional alignment direction with respect to the alignment film) on the liquid crystal panel and the retardation plate, and the direction of the transmission axis on the polarizing plate. 97367.doc -12- 200530675 In the structure of FIG. 4, the incident light from the light source is initially polarized by the third polarizing plate 34 of the switching liquid crystal panel 30. In addition, the switching liquid crystal panel 30 functions as a 1/2 wavelength plate in a disconnected state during 3D display. -In addition, the light passing through the switching liquid crystal panel 30 is then incident on the patterned retardation plate 20. The i-th area 20A and the second area-2 0B of the patterned retardation plate 20 differ in the frictional alignment direction, that is, the direction of the late phase axis, so the light passing through the first area 20A and the second area 20 The polarization states of the two rays of B are different. In the example of Figure 4, pass the first! The polarization axis of the light in the region 20A is different from the polarization axis of the light passing through the second region 20B by 90. . In addition, the patterned retardation plate 20 is set to function as a 1/2 wavelength plate based on the complex refractive index anisotropy and film thickness of the liquid crystal layer 23. The light passing through the patterned retardation plate 20 is incident on the second polarizing plate 15 of the display liquid crystal panel 10. In 3D display, the polarizing axis of the light passing through the first region 20A of the patterned retardation plate 20 and the transmission axis of the second polarizing plate 5 are parallel, and the light passing through the first region 20A passes through the polarizing plate 15. On the other hand, the polarization axis of the light passing through the second region 20B is at an angle of 90 to the transmission axis of the second polarizing plate 5 and the light passing through the second region 20B does not pass through the polarizing plate 15. That is, in the structure of FIG. 4, the parallax barrier function is achieved by the associated optical action of the patterned retardation plate 20 and the second polarizing plate 15, so that the i-th area 20A of the patterned retardation plate 20 becomes a transmission area. The second area 20b is a blocking area. · Light passing through the second polarizing plate 15 will be displayed on the liquid crystal panel 10 of the liquid crystal display panel. · Pixels in the black display layer 13 and pixels in the white display layer will be subjected to different optical modulations. The pixel is optical 97367.doc -13 · 200530675 The withered light will pass through the first polarizing plate 1 i, thereby performing image display. The light that is given a specific viewing angle through the parallax barrier described above passes through the pixels corresponding to the right-eye image and the left-eye image in the display liquid crystal panel 10, thereby making the right-eye image and the left-eye image The ophthalmic images are separated into different viewing angles for 3D display. In addition, in the case of 2D display, the switching liquid crystal panel 30 is turned into a path, and the light passing through the switching liquid crystal panel 30 is not optically adjusted. The light passing through the switching liquid crystal panel 30 is then divided into a light passing through the first area 20a and a light passing through the second area 20B by the patterned retardation plate 20, and then given a different polarization state. However, the situation of 2D display is different from that of 3D display. It does not have the optical modulation effect of the switching liquid crystal panel 30. Therefore, the polarizing axis of the light of the patterned retardation plate 20 will be generated relative to the second polarizing plate. The angular deviation of the left-right symmetry of the transmission axis. Therefore, the light passing through the first region 20A of the patterned retardation plate 20 and the light passing through the second region 20B will pass through the second polarizing plate 15 with the same transmittance, and the patterned retardation plate 20 and the second The polarizing plates 15 do not have an associated optical effect to achieve a parallax barrier function (a specific viewing angle is not assigned), and thus are 2D displays. Also in the above description, the case where the present invention is applied to a 2D / 3D switching liquid crystal display panel is exemplified. However, since the object of the present invention is to prevent crosstalk due to diffraction phenomenon in a 3D display device or a display liquid crystal panel that supplies different images to multiple observers, the present invention can also be applied to 3D type liquid crystal display panel and 3D type liquid crystal display device with switchable liquid crystal panel 3 0 structure (structure dedicated to 3D display), or 97367.doc -14- 200530675 are also suitable for different supply to multiple observers Miaotian Pingxi 々τ ^ k door ~ the display device of the image (can be used to provide different images to the viewers. ^ ", Beibei and general display switching structure, can also be used to provide multiple observers > ^,, should be a dedicated structure for the display of different images).

Here, in the liquid crystal display device of the present invention, in order to prevent the phenomenon of diffraction in the liquid crystal panel for display. The main structure required for the disturbance is the display liquid crystal panel. Therefore, the structure of the display liquid crystal panel of this embodiment will be described in detail below. Among the display liquid crystal panels 10 used in the display device of this embodiment, As shown in FIG. 1, each pixel pattern of the active matrix substrate 14 includes a TFT element 83 and a transparent pixel electrode 86. In addition, each pixel pattern is formed at a position where a plurality of gate lines 80 and a plurality of source lines 81 cross each other to form a matrix. The gate line ⑽ and the source line 81 are insulated and separated by an interlayer insulating film (not shown) provided therebetween. In addition, in the above-mentioned liquid crystal display panel, the liquid crystal capacitance between the pixel electrode 86 and the counter electrode (not shown) is usually insufficient, so an auxiliary capacitance line 82 is provided in parallel with the gate line 81, and the TFT element 83 is drained. The electrode electrode 83c extends to the auxiliary capacitor line to thereby form an overlapping portion, and an insulating film formed therebetween serves as a dielectric body to form an auxiliary capacitor 84 (capacitor for charge retention). The drain electrode 83c of the above-mentioned TFT element 83 is connected to the pixel electrode 86 through an opening in the interlayer insulating film of a part of the auxiliary capacitor 84; the gate electrode "a is connected to a gate that supplies / scans the TFT element 83 to pass / disconnect. The electrode line 80 ′ and the source electrode 83b are connected to the source line 81 for inputting a video signal to the pixel electrode via the TF element 83. The auxiliary capacitor line 82 is provided at the intersection with the source line 81. The insulating film acts as a dielectric to generate a load capacitance. In order to reduce the signal delay of the scanning signal and the image signal caused by the load capacitance, the auxiliary capacitor line on the source line 81 97367.doc -16- 200530675 82 has a small line width In order to reduce the cross-section area and reduce the load capacitance. In addition, in order to ensure the auxiliary capacitance, the auxiliary capacitor 84 itself is as close to the source line 81 at both ends as possible, thereby expanding the width and increasing the area. In other words, the above auxiliary The capacitor line 82 has a thinner line width at the intersection with the source line 81, and a thicker line width in the pixel pattern. The above-mentioned auxiliary capacitor 84 is formed into the shape described above, and even the auxiliary capacitor line 82 on the source line 81 is formed. Refine and reduce the area of the junction, and make the auxiliary electricity close to the source line 81 at both ends to expand the width, so that the shape is between cs (auxiliary capacitor)-source line. Slit opening. In the liquid crystal display panel not constructed in FIG. 1, among the slit openings 88 formed between the Cs_source lines, the biggest difficulty for the largest person is that the main cause of the above-mentioned crosstalk will occur. The liquid crystal display panel of the present embodiment generally proposes two methods to reduce the above-mentioned diffraction phenomenon to suppress crosstalk. The first method to suppress crosstalk is to find the diffraction of light that passes through the slit opening. Conditions, * In the design phase of the pixel W case, try to avoid producing such slit openings. First, this method is explained below. The relationship between the slit opening in the pixel pattern and the crosstalk is simulated. The results obtained are as follows. First, the pixel pattern used in this simulation will be described with reference to FIG. 5. Η 木火 μιη, width 60μηι (for the purpose of explanation, the long dimension, palace ρ 4_, inch are used to indicate) , Source line and gate The size of each line is 3. Therefore, the size of the bismuth in the opening area surrounded by the source line and the polar line in each pixel pattern is 60-3 × 2 = 54 [μΐΏ]. 97367 .doc 200530675: In the pixel pattern, an auxiliary capacitor is formed in the above-mentioned opening area to form a "capacitor auxiliary capacitor line whose line width is thinner than that of the source electrode. Therefore, in the above pixel pattern In the ο (auxiliary Papu source line, a slit opening with a width of x _ is generated. In the following simulation, the width of the opening of the slit is changed within the range of 0 to 27_. And calculate the crosstalk value in each case. Also, the case where the width X_ of the opening is __, as shown in Fig. 5 (b), means that the entire auxiliary capacitor line is formed thick without the slit opening. As shown in Fig. 5 (a), the situation of the opening ^ visibility Xμ427μηm refers to the case where the entire auxiliary valley line is formed thinner without the slit opening. In addition, the above-mentioned crosstalk is generated when a 3D display (or a display of different images is provided to multiple observers) is made by combining a display liquid crystal panel with a pixel pattern and a parallax barrier, so in the following simulation, The gap widths of the parallax barriers are set to 30, 33, and 35, and simulations are performed for these three situations. In addition, the crosstalk value calculated through simulation is dimensionless I defined by the following formula. X. In the formula ⑴, Dark indicates the brightness on the black display side when the black display is performed on one of the right-eye image and the left-eye image and the other is white display. Β1—It is the brightness of the black display when both the right-eye image and the left-eye image are displayed in black. Bright represents the brightness on the white display side when the right-eye image and the left-eye image are displayed either in black or white. The larger the crosstalk that occurs, the higher the brightness of Dark under the influence of the crosstalk, which makes the difference in value larger. Therefore, use 97367.doc * 18-200530675 to measure according to the formula (1) ... The graph shows that the crosstalk value represented by the formula (1) in Table 1 becomes larger. Of course, the brightness' can also be measured and calculated to obtain the crosstalk value. The crosstalk value is Dark-Black Bright-Black. The simulation results are shown in Table 1 below. Besides the results. Also, the so-called simulation here refers to the calculation of the pixel size, openings, substrate thickness, substrate refractive index, wavelength of the light source of the liquid crystal display device used to generate the display image, and even the calculation of the light emitted from the light source based on the left and right eye distances. The direction of the light travels, and the crosstalk value is calculated according to the gap distance and gap width of the optimal patterned retardation plate.

In addition, the patterned pattern of Table 1 is 97367.doc -19 · 200530675 The value calculated by the pixel in Figure 5. Root: Kang's above table! And the results shown in Figure 6, it can be seen that the crosstalk value in the range of the width of the opening is 3 ~ 6 _ is particularly large. From this reasoning, as long as this In the LCD panel for m, it is possible to avoid a width of 5 and 6 = on. In addition, in terms of the crosstalk value, when its value is: 7% of the historical image, it is ordered from 3 to 3 Satoshi from time to time, or it is different for multiple inspectors When the shirt image # is shown, the string I that affects visibility will be excluded. Excluding the range of 3 ~ 6 _ makes the crosstalk value lower than that of plastic. Change ^ P to suppress the shadow of crosstalk II; the result of Γ1 on gate two shows that To ensure that the crosstalk value is lower than, the width X _ Below 2 _ or 7 _ or more, in addition to the results shown in the above fantasy and Figure 6, crosstalk can also be combined, and the range of the opening portion depending on the money is expressed as: (the maximum degree of the opening portion of the pixel ) / (The opening σ of the pixel is adjacent to the sound of the dream house ... If the width x of the diffraction part is taken into account, the same direction is calculated, and the opening part of the pixel is again S4 μΐη. In this case, the crosstalk value reaches 5.6 parts. The range is: the upper opening 037 < (the minimum width of the opening of the pixel is large) < 0.13. The opening 22 of f is different when the 3D display is performed or for multiple observers. To prevent crosstalk from affecting the visibility, just set the width of all the openings in the pixel pattern as follows:, 0 < (the minimum width of the opening of the pixel) / (the opening of the pixel & degree K 0.037; The larger one is 97367.doc -20- 200530675 or 0.130 $ (maximum opening of the pixel * 1 for small visibility) / (maximum width of the opening of the pixel) < 1. In addition, in this implementation In the display liquid crystal panel of the form, the width of the slit opening portion is set in a string If the value is lower than 5.2, it can greatly reduce the adverse effect on visibility during 3D display or when supplying different images to multiple observers for display. In addition, in order to make the crosstalk value lower than 5.2, The range can be set as follows according to the above Table 1: 〇 < (Minimum width of the M mouth of the pixel) / (Maximum width of the opening of the pixel 0.037; or 0.148 $ (Minimum width of the opening of the pixel) / (Maximum width of pixel opening) $ 0.185; or 0.296 ^ (Minimum width of pixel opening π) / (Maximum width of pixel opening) < 1. Or, in order to make the crosstalk value lower than the range of the opening portion of 5.2, it is only necessary to set it to a range other than the following: 2 μιη < (minimum width of the pixel opening portion) < 8 μηι; and 10 μιη < (pixel opening Minimum width of the part) < 16 μm. In this LCD display panel, it is better to avoid the creation of slit openings with a width in the range of 1 to 26 μm, so that the crosstalk value can be lower than 4.8. In this case, there can be almost no crosstalk. Under the influence of it, it can display 3D display with high sharpness or display different images to multiple observers. Also in the above description, the openings formed between the Cs-source lines are exemplified as 97367.doc -21-200530675 as slit openings that cause diffraction phenomena that are the main cause of crosstalk. The position of the slit opening is not limited. For example, when the drain electrode of the tintin device includes a light-shielding metal film, the width of the opening formed between the drain electrode and the source line may also be a position to which the present invention is applicable. The second method for suppressing crosstalk is that in the presence of openings, it will cause crosstalk and adversely affect visibility. Therefore, covering the 3 openings with a light-shielding film is a major reason for crosstalk. Shoot light. Figures ⑷ and ⑻ show pixel patterns in a display liquid crystal panel using this method 2. In the pixel pattern of the display liquid crystal panel shown in FIG. 7 (A), a light-shielding film 89 parallel to the electrode line 80 is arranged to shield the opening formed between the Cs source lines. The width of the light-shielding film 89 is substantially the same as the vertical width of the storage capacitor 84, and it is provided on the opposite substrate side. A light-shielding film 90 covering the TFT element M may be further provided. In addition, the openings formed between the Cs_source lines are shielded, and a light-shielding film such as the light-shielding film 89 shown in Fig. 7 (b) may also be formed so as to cover the openings. The light-shielding M is provided not only on the counter substrate, but also on an active matrix substrate. In addition, in the description of this embodiment, a liquid crystal display panel having an active matrix substrate with a slit ^ 举例 may be used as an example of a display panel in which the above-mentioned crosstalk problem may occur. However, the present invention is not limited to those using a liquid crystal panel as a display panel. ㈣In addition to the liquid crystal panel, the display panel of the active matrix type substrate can also be considered to use, for example, an organic EL panel. Since an organic EL panel is used as a display panel, the same problem may occur as in the case where slit openings are present in the pixel pattern of the panel. Therefore, the present invention can also be applied to the use of organic EL panels and the like are used as display devices for display panels. '' As described above, the display panel of the present invention has a display image generating means for generating a display image corresponding to the inputted image data, and a display image separating means for separating the display image into a plurality of viewpoints simultaneously or in a time-sharing manner. It is characterized in that the above-mentioned display image generating means is an active matrix type display panel, and the width of the opening portion in each pixel pattern of the active matrix type display panel is set as: 0 < (the minimum width of the pixel opening portion) / ( The maximum width of the pixel openings) S 0.037; or (the minimum width of the pixel openings) / (the maximum width of the pixel openings) < 1. According to the above structure, by setting the width of the opening portion in the pattern of each pixel pattern within the above range, the display panel can be used to divide the display image into multiple viewpoints at the same time or in time. The crosstalk value produced by the radio phenomenon is controlled below 5 · 6, which can reduce the adverse effect on visibility. In addition, in the above-mentioned display panel, the width of the openings existing in each pixel pattern of the active matrix display panel is set to: ○ (minimum width of the openings of the pixels) / (maximum width of the openings of the pixels) Width) S 0.037; or 0.148 $ (the minimum width of the opening of the pixel) / (the maximum width of the opening of the pixel is 0.185); or 0.296 $ (the minimum width of the opening of the pixel) / (the maximum of the opening of the pixel) 97367.doc • 23- 200530675 large width) < 1. According to the above structure, by setting the width of the opening portion in the pattern of each pixel pattern within the above range, the display panel can be used simultaneously or in a time-sharing mode. When the display image is divided into multiple viewpoints for display, the crosstalk value due to the diffraction phenomenon is controlled to be less than 5 · 2, which can further reduce the adverse effect on visibility. In addition, 'other display panels of the present invention have corresponding inputs. A display image generating means for generating a display image based on image data, and a display image separating means for separating the display image into a plurality of viewpoints simultaneously or in a time-sharing manner are characterized in that: The above-mentioned display image generating means is an active matrix type display panel, and the width of the opening portion in each pixel pattern of the active matrix type display panel is set to a range other than the following: 2 μπι < (minimum width of the pixel opening portion) & lt 7 μιη. According to the above-mentioned structure, by setting the width of the opening portion in the pattern of each pixel pattern within the above range, the display panel can be used to divide the periscope image into multiple viewpoints at the same time or by Torihito The crosstalk value due to the diffraction phenomenon during the display is controlled to be below 5_6, which can reduce the insensitivity to visibility. In addition, in the above display panel, there are openings in the pixel patterns of the active matrix display panel. The width of the portion is set to a range other than the following: 2μηι < (minimum width of the pixel opening portion) <8_; and 10μηι < (minimum width of the pixel opening portion) < 16_. According to the above structure, by Set the width of the opening in the pattern of each pixel pattern 97367.doc • 24-200530675 degrees within the above range, you can use the above display panel to When the display image is divided into multiple viewpoints for display, the crosstalk value due to the diffraction phenomenon is controlled below 5.2, which can further reduce the adverse effect on visibility.

The panel, and a light-shielding film is used to block the slit openings in each pixel pattern of the active matrix display panel. According to the above-mentioned structure, if there are openings in the pixel pattern, crosstalk due to the diffraction phenomenon may cause crosstalk. In the case where the visibility is adversely affected, the opening portion is covered with a light-shielding film, thereby blocking the diffracted light, which is the main cause of crosstalk, to prevent crosstalk due to the diffraction phenomenon.
